Geophysics has long enjoyed a favorable environment for support. This has been largely due to unfolding opportunities. Geophysics relates to many important national and international matters–raw materials, the sea, weather, natural disasters, and nuclear test detection to name a few. The favorable environment for geophysics also resulted from great leadership, e.g., the activities of such giants as Lloyd Berkner. These leaders were influential in the small elite group of science advisers whose recommendations dominated science decision-making for two decades. They operated effectively through the President's Science Advisory Committee (P.S.A.C.) and through committees of the National Academy of Sciences.
